History
The Will Nullifier was used by Malcolm Donalbain in his mad plot to use Dr. Joanne Tumolo's machine to create amazonian women then equip them with the Will Nullifier collars to make them do his bidding. This plan was foiled by Greer Grant under the guise of the Cat.
Trivia
- Although Zabo Donalbain is later seen as a confused victim in Marvel Team-Up #125 due to being thrown onto the machine created by Dr. Tumolo in the story in which he first appears in The Cat #1 he can be seen wearing a Will Nullifer throughout the story and it is never mentioned. This could be heavily implying that Zabo was always the victim of his brother who was using the device to control him.
